At the 5% level of significance, which variables are statistically significant? If the price of cement per yard increases by 10, what will happen to the estimated quantity of cement demanded? What happens if it will increase by 20%?
A series of tests of fire prevention sprinkler systems that use a foaming agent to quell the fire were performed to determine how long it took (in seconds) for the sprinklers to be activated after the detection of a fire by the system. The system has been designed so that the true average activation time is supposed to be at most 25 seconds. Do the data strongly indicate that the design specifications have not been met? The data for the test are given below: 27 41 22 27 23 35 30 33 24 27 28 22 24

In an agricultural experiment, the effects of two fertilizers on the production of limes were measured. Twenty-three randomly selected plots of land were treated with a brand new fertilizer, and 21 randomly selected plots were treated with an old fertlizer. The number of pounds of harvested limes were measured from each plot. The results are given below. (Round answers to two decimal places.)Data: New Fertilizer Old Fertilizer 412 480 434 472 436 485 418 453 412 470 415 464 412 482 438 466 439 481 443 470 427 472 426 466 439 493 427 471 438 495 430 479 411 467 424 476 419 493 424 485 425 482 437 420 Find a 90% confidence interval for the difference between the mean weight of the harvested limes.margin of error: lower limit: upper limit: Based on the results, is the new fertilizer better than the old fertilizer?

Can pleasant aromas help a student learn better? Hirsch and Johnston, of the Smell & Taste Treatment and Research Foundation, Chicago, asked subjects to work through a set of two pencil and paper mazes six times; three times while wearing a floral-scented mask and three times with an unscented mask. Testers measured the length of time it took subjects to complete each of the six trials. The improvement in completion times, expressed as the percentage change in speed of completion from the first trial to the third trial for each maze, was recorded. (Negative values indicate no improvement with completion times longer for the third trial.). The researchers wanted to determine whether there was more of an improvement in completion times, on average, when wearing a floral-scented mask. Data: % Unscented % Scented 33.07 43.13 9.31 -3.66 28.41 42.86 15.26 30.65 21.86 16.42 7.37 16.37 20.44 3.17 -23.43 27.06 -3.35 27.25 32.78 -0.17 22.77 37.3 -6.77 35.89 19.64…
